Thanks for looking into this!

Yes, it does not fail each time.
the test that fails is test-export.

x86_64

2.17.1, the one in unstable. But it is the same with other versions of PARI.

I do something like

./Configure --mt=pthread
make gp -j12
for i in `seq 1 100`; do make test-export || break; done

The only libc I see failure is 2.41, even I if use binaries built on bookworm and
run them on sid.
